Abstract
Active shape models can be applied to tracking non-rigid objects in video image sequences. Traditionally these
models do not include color information in their formulation. In this paper, we present a hierarchical realization of an
enhanced active shape model for color video tracking and we study the performance of both hierarchical and non-
hierarchical implementations in the RGB, YUV, and HSI color spaces.

1. Introduction
The problem of tracking people and recognizing
their actions in video sequences is of increasing
importance to many applications (Haritaoglu et al.,
2000; McKenna et al., 1999; Plaankers and Fua,
2001). Examples include video surveillance, human
computer interaction, and motion capture for an-
imation, to name a few. Special considerations for
